Review on STADEA Premium Diamond Polishing GRANITE Abrasive & Finishing Products in Finishing Products by Donald Cummings

You are excellent. They worked on my marble as advertised. They say they run between 2400 and 4800 rpm. I would recommend (at least on Marble) to run them on the slow side. Since this was my first time doing this, I ran over the high side and noticed I was getting round scratches on my marble. A friend of mine who is doing the repair advised me to reduce the RPM to a minimum and move the grinder more. That helped. So I pass it on. Also use plenty of water. do it. I would buy them again and recommend them to friends.
